A breast lift is intended to correct a ptotic breast, independently of the volume correction. In ptotic breasts the nipple position is at the level of the inframamary fold or lower. In light to moderate cases it can be accomplish only by adding volume as this will give one to two centimetres lift. In the other ones we have also to take skin out, in order to get the desire lift.
Breast augmentation is intended to add volume. It is related to size, not to the nipple position. In most cases, alone, it cannot correct a ptotic breast.
In some cases we just have to combine both procedures. We called it a “mastopexy with an implant”
